Question

If 15 cos A-7sinS=0 then the value of sinA+cosA/2cosA - sin A=

Answer 1

Step-by-step explanation:

By the given question 15CosA-7SinA=0 By solving this we get

$15CosA=7SinA$

$SinA=\frac{15CosA}{7}$

By the obtained result; the given question is to find    $\frac{SinA+CosA}{2CosA-SinA} = ?$

$\frac{SinA+CosA}{2CosA-SinA}=\frac{\frac{15CosA}{7} +CosA}{2CosA-\frac{15CosA}{7} }$

                  $=\frac{\frac{22CosA}{7} }{\frac{-CosA}{7} }$

                 $=-22$

Therefore our final answer is -22
